Repeated crashes during clean install of XUbuntu 11.10

[Albin T]

I've been trying to create a clean install of Xubuntu 11.10 using the desktop i386 installer. The installer has crashed every time but not always in the same place. The machine completely froze a couple of times while "configuring hardware" but the last time it crashed but didn't freeze so I could send this bugreport. The last time I didn't check "download updates" or "install third party" check boxes.

I am running xubuntu 10.10 and 11.04 on the same machine. 10.10 runs fine but 11.04 freezes randomly. Memtest does not report any problems. I have successfully installed 11.10 on a different machine using the same iso file on the same external hdd.

Can you please boot the CD/USB disk again, and press a key when you see the "accessibility options = keyboard" image? Select the "Check CD for defects" option and do report back on whether it finds any.

Thanks!

I ran the live cd from an external harddrive using the Grub2 feature of booting directly from an iso using a custom grug.cfg on the external hdd. I.e. I installed grub2 on the external hdd bootsector, customised /boot/grub/grub.cfg and added the iso to the external hdd.

There was no initial screen where I could check for defects but I did compare the md5 of the iso file (on the external hdd) to the ones at:
http://se.archive.ubuntu.com/mirror/cdimage.ubuntu.com/xubuntu/releases/11.10/release/MD5SUMS

It may be a hardware issue though. I finally managed to install after setting the bios to "safe-defaults" and using a different partition on the hdd. If it helps, I can try to recreate the problem again to determine if it was the bios settings or the hdd.
